feat(render): names reach the view and every emitter

The view's name is now the RESOLVED display string and slug is untouched,
so machine formats carry both -- a script keeps the stable key, a human
reads the name.

name is a plain string, not a lang-keyed object. That removes the
shadowing hazard outright: a dotted {{name.la}} used to fall back
WHOLESALE to the enclosing month's name.la and print Ianuarius on every
unnamed day, which is how a printed booklet came to show the month where
the feast belonged.

weekday, season, rank and colour all gain localised companions, because a
calendar in a language needs more than feast names, and templates gain a
term vocabulary so fixed strings need no template edit to translate.

Asserted over a whole year: no day renders its slug as its name.

Beyond the brief's own code sample:

- comm_value's own name is now resolved through the same lang.celebration
  table too (not only the observed day's), because Task 8's own ordo
  template interpolates a plain {{name}} inside {{#comms}} -- an Obj there
  would render silently blank. A commemoration slug without Latin
  coverage still degrades to the slug, same as everywhere else in this
  system; that is a lang/la.ini DATA gap (113 of 327 sanctoral slugs,
  measured), not a regression this task introduced.

- bin/main.ml's emit/table/publish call sites needed ~lang to compile at
  all, which is collateral from the of_days signature change, not this
  task's own file list. Rather than pass Lang.raw and ship the very
  slug-as-name defect this branch exists to fix, they load the shipped
  Latin table by the same probe order data_dir() already uses -- a
  deliberate, commented BRIDGE that Task 6 replaces wholesale with real
  --lang/--raw/config resolution. bin/dune gained colitur_naming
  accordingly.

- test/cli.t needed two related fixes to stay green: the CSV header/row
  example, and a table/LaTeX escaping demonstration that relied on the
  kernel's own English name for Sts Peter & Paul -- gone from the view
  now that name resolves through lang tables only, and the Missal's own
  Latin spells the feast with et, never an ampersand. Escaping itself is
  still proved live on 2035 data in test_emit.ml.

- Both schemas gained the new day/week/top-level keys (season_name,
  weekday, rank_name, colour_name, term, weekday_headings, month_num,
  month_name), not only the name shape change; schema/colitur-v1.xsd
  verified against real emitted XML via xmllint (make check-schema).

Render/golden's 9 cases (the shipped ordo/grid templates, all six
flavours) now fail as expected: their old {{name.la}} / {{#name}}...
idiom finds nothing on a plain string. That is Tasks 8/9's own scope to
rewrite, per the plan's own pre-flight conflict scan -- not fixed here,
and not silently pinned by regenerating goldens off broken output.

495 tests run (490 + 5 new), 486 pass; the 9 failures are exactly
Render/golden's ordo/grid cases.
